2-Decarboxy-2-hydroxy-methyl-5-oxa-ω-phenoxy-PGD1 compounds

ABSTRACT

This invention comprises certain analogs of the prostaglandins in which the C-1 carboxyl is replaced by a primary alcohol. Also provided in this invention, are novel chemical processes useful in the preparation of the above prostaglandin analogs. These prostaglandin analogs exhibit prostaglandin-like activity, and are accordingly useful for the same pharmacological purposes as the prostaglandins. Among these purposes are blood pressure lowering, labor induction at term, reproductive-cycle regulation, gastric antisecretory action, and the like.

The present application is a divisional application of Ser. No. 647,357, filed Jan. 8, 1976, now issued as U.S. Pat. No. 4,055,602.

The present invention relates to prostaglandin analogs, for which the essential material constituting disclosure therefor is incorporated by reference here from U.S. Pat. No. 4,055,602, issued Oct. 25, 1977.
